To all whom t may concern:

Beit known that I, WILLIAM L." SEBRING, a

citizen of the United States, residing at 0010-'l Vrado Springs, in the county of El Paso and commonly used on freight-cars, in which the seal must be broken before the door can be opened; and it consists in the features hereinafter described and claimed.

1n the accompanying drawings, Figure 1 is a sectional side elevation through one form of my device, showing the seal in place and the parts in their locked position.` Fig. 2 is a similar view, showing the bolt turned for removal and the seal broken. Figs. 3 and 4 are perspective views of the frame and bolt, respectively; and Fig. 5 is a. front elevation of a seal.

Similar characters indicate like parts throughout the several gures of the drawlngs.

The letterS designates a frame,which may have a back plate 10, provided with openings 11 12 to receive bolts for securing it to the car, the opening 11 being shown as a vertical elongated slot to permit its application to various cars without the necessity of boring new holes therein. From'a point near the bottom of the frame projects the usual staple 13 to receive the hasp 13a of `a car-door, and above this is a bracket or bolt-support 14, which may be conveniently cast with the frame. Through the bracket is a vertical cylindrical opening 15 to receive the bolt B, which also passes down through an opening 16 in the staple in alinement with opening 15.

At the front of the bracket are formed ways 17, serving as a frame or one portion of a holder to receive a seal S', consisting of a plate of suitably-baked clay or'other frangible material, which may rest upon a lug 18 near the bottom of the' holder. Through the rear of the bracket is a cylindrical opening 19, preferably counterbored to receive and retain against too greatinward movement a headed pin 20. This pin is held normally with its point projecting into the opening 16 by a spiral spring 21, seated in the space between the rear of the head of the pin, and a slide or movable member 22, operating inways at the back of the frame, which slide serves to keep the spring and pin in place when the device is not fastened upon a car.

The bolt B consists more essentially of the bolt portion proper or shank 23, operating in the openings 15 and 16 of the bracket and staple, and ahead portion 24. In the head is an elongated recess 25 to receive or hold the upper edge of the seal and form a second part of the holder therefor. Projecting from the head portion 24 of the bolt is ahandle 26, by means of which the bolt is rotated and moved longitudinally in the openings provided for it in the frame. The bolt-head 24 also carries a projection 27, which contacts with any extending face 28 from the frame when the The projection 27 serves to limit the rotary movement of the bolt in one direction and also acts as a guide for the longitudinal movement of the'loolt-head when `the bolt is being moved downward into position to inclose a seal. A projection 29, depending from the under side of the bolt-head 24, rests, when the seal is inclosed by the frame and bolt-head, in one of the recesses 30 in the bracket at the rear of the seal, and when the bolt is rotated the projection29 engages with the seal and fractures it. At the back of the bolt-spindle is a recess 31 to receive the end of the pin 2O when the parts are in their lockedl position. This recess is open at 32 to permit the pin to leave it when the bolt is rotated, and a curved or inclined face 33 extends frorn this opening, down which the end of the pin may ride. the bolt, at the rear, is a recess 34, having an inclined upper wall 35 and a square lower wall or shoulder 36. i

In use, the bolt being raised, the door-hasp is placed over the staple, and the seal, which may be suitably inscribed with a record- Near the lower end of v number, is inserted in the bracket. The bolt y IOC) it is necessary to break the seal, and this is ei'ected by rotating the bolt by its handle, whereupon the seal will be shattered by the shearing action of the Itwo parts of the holder and the projection 29 will throw out the broken pieces. At the same time the pin will pass out of the open side 32 of the recess and the bolt may be freely raised, the pin riding over the inclined face 33. When it has been raised sufficiently, the pin will pass in the recess 34, which holds the bolt up, while its shoulder 36 prevents the complete withdrawal of the bolt. In furtherv use the same action is repeated with a new seal, the inclined wall of the recess 34 allowing the lowering of the bolt upon pressure being applied. If desired, the lower end of the bolt-shank may be perforated at 37 to permit the application ofthe ordinary wire seal.

Having thus described my invention, I claim- The combination with a bolt-support provided with a seal-seat and having a bolt-receiving opening, of a spring-pressed pin eX- tending into the bolt-receiving opening, and a bolt adapted to retain a seal in said seat slidable and rotatable in said opening and provided near the top with a recess adapted for engagement by the pin when the bolt is in operative position and provided near the bottom with a recess disalined from the upper recess and presenting a shoulder at the bottom vfor engagement by the pin to prevent the withdrawal of the bolt and an upward ineline with which the pin will engage to support the bolt in raised position, but which will permit the descent of the boltwhen force is applied thereto.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

WILLIAM L. SEBRING.
